Heartnut Tree Information
Heartnut trees can grow to 50 feet tall (15 m.) with a spread of 65-100 feet (20-30.5 m.). They are hardy to cold and most pests. They get their name from their prolific production of a nut that looks, both inside and out, like a heart. The nuts taste similar to walnuts and are extremely hard to crack open. Growing heartnuts in well-drained soil will produce the best results, but they will grow in loamier soils.
Growing and Harvesting Heartnuts
Growing heartnuts is not difficult. You can plant the nuts directly in the ground or graft them. Grafted trees should start producing nuts in 1 to 3 years, while trees grown from seed can take as long as 3 to 5 years. Even then, it will probably be 6 to 8 years before they make enough nuts for a real harvest. Harvesting heartnuts is very easy – for a period of about two weeks in the autumn, the nuts will drop naturally to the ground. Make sure to pick them up within a few days, or they can rot. Dry the nuts in a dark, airy place to preserve them in their shells. If you want to shell them immediately, you will probably need a hammer or a vise. Harvesting heartnuts from their shells is notoriously difficult. Once you get through the hard shell, however, it’s worth it for the tasty meat and conversation that can come from it.
